May 22nd 2008 3:10PM It means those classes skills/talents are not available past 70 right now in the alpha. Any info that is released on classes/tradeskills not implemented yet in Alpha is pure datamining and not yet seen in-game. Shamans are listed as released in the patch notes, however, it seems they are not(or info not leaked yet). They will stagger the release of future classes/tradeskills in future patches. Hope this helps.

Also, as a mount collector, this could get expensive unless the Primal Might is taken out of the current Riding Crop pattern.
